Free Heart Diagrams

Heart is a really important organ in human’s body, and if you wish to learn more about this beating organ, use these heart diagrams as your learning as well as evaluating media. The heart in a human body is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries. The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. Look at the first heart diagram below to help you digest what you just read.

There are four chambers in human body’s heart: the right atrium receives blood from the veins and pumps it to the right ventricle; the right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen; the left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle; the left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.
